Rship where 2 or more independent variables/ dependent variables or both are tested.
Simple hypothesis aka ______
Bivariate
Complex hypoth aka ______
Multivariate
Def null hypoth
Predicts no relationship bx variables
Def research hypoth
States the expected rship bx variables
The null hypoth is subjected to _____
Statistical analysis
Def Nondirectional hypoth
Merely predicts that a rship exists
Direction of the hypoth not present
Def Directional res hypoth
Researcher predicts the type of rship that is expected
Advantages of directional hypoth
Make researchers expectations clear
Allow more precise testing of theoretical propositions
Allow the use of one tailed statistical tests
Hypoth criteria ( 6)
Written in a declarative sentence Written in the present tense Contain the pop Contain the variables Reflect prob statement, purpose statement, or res question Be empirically testable
